Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0439 advisory.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163)

* kernel: use after free in unix_stream_sendpage (CVE-2023-4622)

* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)

* kernel: eBPF: insufficient stack type checks in dynptr (CVE-2023-39191)

* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)

* kernel: Race Condition leading to UAF in Unix Socket could happen in sk_receive_queue (BZ#2230094)

* kernel: nfp: use-after-free in area_cache_get() (CVE-2022-3545)

* kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858)

* kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)

* kernel: NULL pointer dereference in can_rcv_filter (CVE-2023-2166)

* kernel: Slab-out-of-bound read in compare_netdev_and_ip (CVE-2023-2176)

* kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race (CVE-2023-3567)

* kernel: use-after-free in netfilter: nf_tables (CVE-2023-3777)

* kernel: use after free in nft_immediate_deactivate (CVE-2023-4015)

* kernel: A heap out-of-bounds write (CVE-2023-5717)

* hw amd: Return Address Predictor vulnerability leading to information disclosure (CVE-2023-20569)

* kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment (CVE-2023-38409)

* kernel: use-after-free in l2cap_sock_release in net/bluetooth/l2cap_sock.c (CVE-2023-40283)

* kernel: SEV-ES local priv escalation (CVE-2023-46813)

* kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

* kernel: NULL pointer dereference in dpll_pin_parent_pin_set() in drivers/dpll/dpll_netlink.c (CVE-2023-6679)
